Key Features

• Comprehensive step-by-step flow measurement process.
• Detailed roles and responsibilities for each worker involved.
• Safety guidelines for maintaining appropriate hydraulic pressure levels.

Benefits

• Ensures accurate flow and pressure measurement for optimal system performance.
• Improves safety by clearly defining roles and expected actions during the procedure.
• Helps maintain hydraulic systems within safe operating limits.

Usage Recommendations

• Ensure all personnel are briefed on their roles: Work Supervisor, Operator, and Measurement Recorder.
• Monitor hydraulic oil temperature and engine performance for smooth operations.
• Adhere to pressure limits to prevent damage to equipment and ensure safety.

Flow Measurement Process

Manual Extract: Flow measurement

1. Position the workers as specified:
   • Worker 1: Work supervisor, responsible for pressure adjustment.
   • Worker 2: Operator.
   • Worker 3: Records flow and pressure measurement.
2. Check the hydraulic oil temperature on the monitor (50u00b0C, 122u00b0F) and ensure normal engine rotation and pump current.
3. Operator signals the arm-out relief operation to Worker 1.
4. Worker 2 lowers the arm-out port relief with a minimum pressure of 24 MPa (240 bar, 3481 Psi) (P1 + P2).
5. Initiate flow measurement process.
6. Conduct arm-out relief operation.
7. Record data measured in increments of 2.0 MPa (20 bar, 290 Psi) from 24.0 to 76.0 MPa (240 to 760 bar, 3481 to 11023 Psi), ending at maximum pressure.
8. Remove the flow meters before exceeding the pressure gauge’s maximum pressure (40 MPa, 400 bar, 5802 Psi).
9. Reset the arm-in port relief valve to its normal pressure setting, consulting the “Pressure Adjustment” section for details.
10. Remove all pressure gauges and additional equipment, restoring the system to normal operations.
